PLOW.

SPECIFICATION forming part of Letters Patent No. 571,688, dated November17, 1896.

Application led February 29, 1896. Serial No. 581,385. (No model I To@ZZ whom, it 11i/Ly concern.'

Be it known that I, STERLING I. Ricnnoivn, a citizen of the li'nitedStates, residing at Billings, in the county of Christian and State ot'Missouri, have invented a new and useful Plow, of which the followin isa specification.

This invention relates to an improvement in plows; and the object inview is to produce a simple and eiiicient plow which may be used eitheras asingle or double plow or as a clod breaker and pulverizer, theseveral standards which comprise the plow heilig so mounted withrelation to the beam that the)T may be adj usted,as to the anglefor regulatin g the depth to which the shovels enter the ground.

'lhc invention also has Afor its object to provide novel means wherebythe plowhandles may be raised and lowered to suit the requirements ofthe operator.

The invention consists in an improved plow embodying certain novelfeatures and details of construction and arrangement of paris, ashereinafter fully described, illustrated in the drawings, and finallypointed out inthe claims hereto appended.

In the accompanying drawings, Figure l is a perspective View of a plowconstructed in accordance with the present invention. Fig. 2 is avertical longitudinal section through the rear portion of the plow beam,&c. Fig. 3 is a plan view of the same with the plowhandlcs partly brokenaway. Fig. 4 is an enlarged detail perspective view oi' one of the rearstandards and its adjusting-clip. Fig. 5 is a detail view ot' the lowerextremitbv of one of the beam extensions. Fig. G is a detail perspectiveview of one of the shovel clips or holders. Fig. 7 is a detailview ot'one of the friction-plates for holding the handle-braces. Fig. S is adetail view of one ot' the spacingsleeves of the beam extensions.

Similar numerals of reference designate corresponding parts in theseveral ligures of the drawings.

Referring' to the accompanying drawings, l designates the plow-beain,which in the present instance is constructed ot' hard wood and providedwith suitable handles The handles are pivotally connected at theirforward extremities to the bea-1u l by means of a transverse bolt 3passing through such extremities and through the beam. From theirpivotal point the handles diverge upwardly and rearwardly, bein g spacedapart by a horizontal strut il. and firmly secured by a hori Zontaltie-bolt 5 or in any other convenient manner. Attached to the beam at apointbetwcen the pivotal connection of the handles and the rear end oithe beam is a forward and centralV standard (i. This standard comprisestwin side portions 7 et bar metal spread apart at their upper endssuiiiciently to stride the beam and connected thereto by means of atransverse bolt S. The lower ends off the parts '7 are united. in angTconvenient manner, space being left, however, between said parts for abolt l0, by means of which the shovel ll is attached to the lower endot' the standard.

A clip l2 is provided in connection with the shovel ll. `for the purposeof holding the latter stationary and preventing the twisting thereof.This clip or holder comprises a reduced shank port-ion which passesbetween the parts 7 and a lower expanded end which lies against the rearedge of the standard and is perforated to receive the bolt lo. The clip12 at its forward end is also expanded to forni a transverse shoulderlil, which abuis against the upper edge of the shovel and prevents thesaine from twisting. The bolt l0, passing through the shovel and clip orholder, serves to lock both firmlyv in place. The standard (i isadjusted as to its angle with relation tothe beam by means of arearwardly and upwardly inclined brace il, the upper and rear portion otwhich is deflected into a horizontal plane and caused to lie beneath thebeam l and bear against a wearnplate l5, attached to the lower edge ofthe beam or mortised into the same, as shown.

An eyebolt lf3 passes verticallyv through the rear end of the beam andreceives the brace ll through its eye, the upper end of the boltreceiving an. adjustin and tightening nut which is seated against awear-plate 17, located upon the upper edge of the beam. The forward endot the brace ll being pivotally connect-ed to the forward standard byloosening the eycbolt 15 the brace is permitted to .slide therethroughand the standard to be' correspondingly adjusted as to its angle.llvhen' brought to the proper pitch,

TOO

the eyebolt may be tightened and the standard so held.

A pair of handle-braces 18 are arranged upon opposite sides of the beam,the same being composed of stout rods or wires, the lower ends of whichare pivotally received on the bolt S, above referred to, passing throughthe standard, the upper ends of said braces being received througheyebolts 19, which pass transversely through the handles 2 of the plow.Serrated gripping or friction plates 20 are located upon the inneradjacent faces of the handles, being held in place by the eyebolts 19,which pass through them. By tightening the eyebolts 19 the handle-bracesare caused to bite against the serrated faces referred to, and thelongitudinal slipping of the braces is thus effectually prevented.

21 designates what may be termed a pair of beam extensions, which areformed of metal and are in the shape of elongated bars or straps. Theseextension pieces abut against the side faces of the beam at theirforward ends and are secured by the pivotal bolt of the handles. Alittle in rear of such connection the extension-pieces are deflectedlaterally in opposite directions and then extended in parallel relationto the beam, or substantially so, and are spaced at the proper distancefrom the beam by means of spacingcollars 22, the outer ends of which arerecessed to receive the extension-pieces 21. A through-bolt 23, passingentirely through the extension-pieces, spacing-sleeves, and beams, holdsthe structure rigid. The rear ends of the extension-pieces are givensemicircular bends '24, so as to cause the extremities thereof toproject forward, and each of said extremities is formed with atransverse slot 25 for a purpose that will appear.

Upon each of the extension-pieces 21 is pivotally mounted a standard 27.This standard is formed in a similar manner to the forward standardabove described, comprising spaced bars connected at their lower endsand having a shovel connected thereto. This standard straddles theslotted end of its respective extension-piece and is connected theretoby means of a transverse bolt 29 passing through the standard andworking' in the slot 25.

30 designates a clip or sleeve which surrounds the extension-piece 21and is capable of being held at any point thereon by means of aset-screw 31. At its under side the clip 30 is provided with aperforated ear which lies between the upper ends of the standardbars andis pivotally connected thereto.

32 indicates a wedge or wear plate arranged within the opening of theclip for regulating the size of such opening to the extension-piece 21..By means of the construction just described the standard may be rockedupon its pivotal connection with the extension-piece, in which movementthe clip 30 will slide upon said extension-piece, the slot in the end ofthe latter permitting the standard to rise and fall and thus allowingthe clip to move partially around the U-shaped bend in the rear end ofthe extension-piece. l/Vhen the desired adjustment is obtained, bytightening the set-screw 31, the standard may be held fixed. v

From the foregoing description it will be seen that a very simple andefficient plow is obtained,which by omitting the central standard andshovel may be used as a double plow, or by omitting the side shovels maybe used as a single plow; also that by employing all of the shovels theimplement may be used as a clod breaker and pulverizer; also that by thevarious adjustments referred to the shovels may be set to penetrate thesoil to any desired depth and the handles may be raised or lowered tosuit the convenience of the operator.

It will also be apparent that various changes in the form, proportion,and minor details of construction may be resorted to without departingfrom the spirit or sacrificing any of the advantages of this invention.

Having thus described the inventiomwhat is claimed as new is- 1. In aplow, the combination with the plowbeam, and the plow-handles pivotallyconnected directly thereto, of friction-plates arranged upon the inneradjacent faces of the handles and having transverse serrations orcorrugations, a pair of handle-braces also having pivotal connectionwith the beam and extending across the serrations or corrugations of thefriction-plates, and clamping-eyebolts passing through said handles andhaving the braces slidingly engaged thereby, whereby the braces may beclamped against said friction-plates, substantially in the manner andfor the purpose described.

2. In a plow,the combination with the plowbeam, of a laterally-disposedbeam extensionpiece having its rear portion recurved or formed with aU-shaped bend and provided at its extremity with an oblique slot, a standard slidingly fulcrumed on such extremity and having its pivotal boltor pin working in said slot, anda clip having pivotal connection withthe standard and a sliding engagement with the extension-piece,substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
